coverRisk ShieldBe Careful of Market Makers: (You Can’t Beat Them)By Mehrzad Abdi | 12 May 2025

Introduction

In modern financial markets, market makers play a crucial role by providing continuous bid and ask quotes, thus ensuring liquidity and efficiency. They are essential to the operation of exchanges, but they are not mere neutral facilitators. Instead, market makers are sophisticated, well-capitalized institutions (or sometimes even proprietary trading desks) that can leverage advanced technology and statistical models to manage risk and profit from the spread between buy and sell prices. While their activity is crucial to market stability, the power they wield makes them formidable opponents for individual traders who lack comparable resources.

This article examines why individual traders must “be careful” when interacting with market makers. It outlines how market makers function, the inherent disadvantages for retail traders, and risk management strategies that are strongly recommended. In exploring these topics, reference is made to well-established books in the field, such as Larry Harris’s Trading and Exchanges, Jack D. Schwager’s Market Wizards, Edwin Lefèvre’s classic Reminiscences of a Stock Operator, and Alexander Elder’s Trading for a Living. These texts collectively highlight that in the realm of modern trading, the terrain is often tilted in favor of market makers—and that traders must account for this imbalance when crafting their strategies.

1. Understanding Market Makers

1.1 Who Are Market Makers?

Market makers are entities—ranging from dedicated trading firms to large banks—that commit to providing liquidity by standing ready to buy and sell securities at all times. Their primary objective is to facilitate smoother transactions by continuously quoting prices for the securities they cover. In doing so, they earn profit from the difference between the bid (buy) and ask (sell) prices, often referred to as the “spread.”

Larry Harris in Trading and Exchanges describes market makers as “the lubricants of financial markets” (Harris, 2003). Their activities are indispensable for price discovery and mitigating excessive volatility during periods of low liquidity. Nevertheless, while liquidity provision is beneficial for orderly trading, the inherent conflict of interest between market makers—who benefit from frequent transactions—and individual traders—who often trade in smaller volumes and at less advantageous prices—presents considerable risk.

1.2 The Dual Role: Facilitators and Adversaries

Market makers play an ambiguous role. On one hand, they serve as facilitators who ensure that buyers and sellers can trade whenever they desire. On the other hand, they act as adversaries that can profit from the inevitable mispricing or delays by individual traders. Edwin Lefèvre’s Reminiscences of a Stock Operator provides a narrative illustration of the challenges faced by traders trying to outsmart more experienced market participants who benefit from superior information and market access (Lefèvre, 1923).

While market makers are integral to keeping markets liquid, their structural advantages—such as access to order flow information and faster execution speeds—mean that even well-informed individual traders may not effectively “beat” them. This realization leads to an important question: if you cannot beat the market makers, how do you avoid falling victim to their inherent advantages?

2. How Market Makers Operate

2.1 Market-Making and the Bid-Ask Spread

The core function of a market maker is to quote both bid and ask prices for securities. By continuously doing this, they create a spread, which is the primary source of profit. For example, if a market maker is willing to buy a stock at $100 (bid) and sell it at $100.10 (ask), they capture $0.10 per share traded. This setup is efficient in highly liquid markets, but it also signals a potentially steep cost for traders executing orders against the market maker’s quotes.

Jack Schwager’s Market Wizards highlights that many successful traders eventually learn that the true challenge is not just about predicting market movements but also about trading within a system where market makers are actively managing the spread and the flow of orders (Schwager, 1989). The competitive edge of market makers is not limited to the spread alone—they often have cutting-edge technologies that analyze micro-level market data in real time, enabling them to adjust quotes almost instantaneously.

2.2 Order Flow and High-Frequency Trading

In today’s fast-paced markets, much of market making is conducted by high-frequency trading (HFT) firms. These firms capitalize on even the smallest price discrepancies that may exist only for microseconds. HFT strategies employ algorithms that can process vast amounts of data far quicker than any human trader can. This edge allows market makers to gauge market sentiment and adjust their pricing accordingly.

In Flash Boys, Michael Lewis describes how technological advancements have allowed certain market participants to operate at speeds that render traditional trading almost obsolete for many retail investors. Although Lewis’s work is controversial in some respects, it underscores an important point for individual traders: when competing against market makers armed with superior speed and analytics, one’s ability to secure a favorable trade diminishes significantly. As such, the key takeaway is not to try and out-trade market makers but rather to recognize their influence and adjust one’s risk and exposure accordingly.

2.3 Risk Transfer and Asymmetry of Information

One of the fundamental principles of market making is the transfer of risk from the market maker to the trader. Market makers are experts in managing risk through techniques such as hedging and portfolio diversification. Their underlying algorithms continuously evaluate market conditions and adjust pricing to mitigate the risks of holding inventory. In contrast, individual traders often find themselves on the wrong side of trades, absorbing more risk than they intend.

John C. Hull in Options, Futures, and Other Derivatives describes how derivative instruments are frequently used by market makers to hedge their positions, thereby reducing the adverse impacts of large price swings (Hull, 2017). This asymmetry places individual traders at a disadvantage because while market makers can offset risk, they design their strategies to capture the bid-ask spread and profit from volatility that individual traders may encounter unexpectedly.

3. Risks Faced by Individual Traders When Dealing with Market Makers

3.1 Adverse Selection and Information Asymmetry

One of the primary risks individual traders face is adverse selection. Adverse selection occurs when market makers possess more reliable information than their counterparts. Their advanced data analytics and real-time order flow processing provide them with insights that retail traders simply cannot obtain. This imbalance means that by the time a trader becomes aware of a particular market movement, the market maker has already adjusted the prices to account for it.

Adverse selection can result in “slippage” — the phenomenon where a trader’s order is executed at a less favorable price than expected. Larry Harris explains in Trading and Exchanges that the bid-ask spread is not merely a cost, but a reflection of the informational asymmetry that exists in markets (Harris, 2003). When individual traders step into the market without accounting for these dynamics, they often find themselves paying a premium due to the market maker’s adjustments.

3.2 The Illusion of Control: Overtrading and Emotional Responses

A common pitfall for individual traders is overtrading, particularly when they feel that they are in direct competition with market makers. The sense of urgency to “beat the market” often leads to impulsive trading decisions—a behavior that is well-documented in Trading for a Living by Alexander Elder. Elder explains that the psychological pressures of a fast-moving market can lead traders to make decisions that are not aligned with their overall strategy, ultimately resulting in significant losses.

The rapid-fire environment in which market makers operate sometimes induces an emotional response in individual traders. Faced with rapidly changing bid-ask spreads and sudden price movements, traders may be tempted to react without adequate analysis, thereby exacerbating their exposure to risk.

3.3 Execution and Transaction Costs

Execution risk is another area where individual traders can be disadvantaged. Even when a trader has a well-thought-out strategy, delays in order execution—due in part to the high-speed environment of market makers—can have a detrimental impact on the profitability of the trade. Execution delays, combined with wider bid-ask spreads for less liquid securities, often result in a higher transaction cost for the trader.

Market makers, who are constantly fine-tuning their execution algorithms, typically secure orders at optimal times. This creates a double bind for retail traders: not only do they face the cost of the spread, but they also endure the cost of execution slippage, further reducing their profit potential.

3.4 The Risk of Manipulative Practices

There is a concern among some market participants that market makers might engage in practices that deliberately disadvantage individual traders. Although outright manipulation is illegal in regulated markets, the practice of “pinging” (sending small orders to detect large hidden orders) or “layering” (placing orders with no intention of execution to move the price) have been topics of debate. While such tactics are generally scrutinized by regulatory bodies, the mere possibility of these practices means that individual traders must always be cautious.

Michael Lewis’s Flash Boys provides an insightful, if sometimes controversial, account of how speed and technology can create an uneven playing field, leaving individual traders vulnerable to tactics that are difficult to detect in real time (Lewis, 2014). Such practices, real or perceived, reinforce the need for a prudent and well-structured risk management approach.

4. Implementing Robust Risk Management Strategies

4.1 The Fundamentals of Risk Management

Given the multi-faceted risks associated with market makers, it is imperative for individual traders to establish a robust risk management framework. A core principle of risk management in trading is to understand and accept that one cannot consistently “beat” a market structure that favors professionals with superior technology and resources.

Risk management begins with the establishment of clear objectives, including setting limits on the amount of capital risked per trade. In Trading for a Living, Alexander Elder emphasizes the importance of position sizing, stop-loss orders, and disciplined trade management as essential components to mitigate risk (Elder, 1993). Without such protective measures, traders expose themselves to potentially catastrophic losses in an environment where market makers continually adjust and adapt.

4.2 Position Sizing and Stop-Loss Orders

One of the simplest yet most effective risk management tools is the use of proper position sizing. By limiting the size of any single position relative to one’s overall capital, traders can ensure that no single adverse market move leads to disproportionate losses. Stop-loss orders, which automatically exit a trade at a predefined level, are a vital defensive tool that protects against unforeseen market movements.

Larry Harris underscores in Trading and Exchanges that the unpredictable nature of order flows and price movements demands that traders use stop-loss orders not only to protect gains but also to safeguard capital (Harris, 2003). When competing against market makers, ensuring that losses are contained is crucial; even experienced traders can fall victim to fleeting market anomalies if they are overexposed.

4.3 Diversification and Hedging

Diversification—allocating capital across different instruments, sectors, or asset classes—is another cornerstone of effective risk management. Relying on a single market or strategy that is heavily influenced by market makers can compound risks, especially during periods of market stress. Diversification not only mitigates individual trade risk but also reduces systemic exposure in volatile conditions.

Hedging, using derivative instruments such as options or futures, is another advanced technique to offset market risk. John C. Hull’s Options, Futures, and Other Derivatives provides an in-depth exploration of hedging strategies that can help traders manage the risk of adverse price movements (Hull, 2017). For individual traders, using hedging strategies to protect against market volatility—particularly during periods when market makers are actively exploiting imbalances—can be an invaluable strategy.

4.4 Understanding Volatility and Market Conditions

Effective risk management also involves a nuanced understanding of market volatility. Market makers can rapidly adjust spreads in anticipation of volatility, and periods of high volatility can lead to dramatic price swings, exacerbating execution risk for individual traders. Tools such as the Average True Range (ATR) or volatility indices (e.g., VIX) can help traders gauge the current market condition and adjust their strategies accordingly.

Sheldon Natenberg’s Option Volatility and Pricing stresses the importance of volatility analysis in managing risk. Natenberg explains that in an environment where market makers are actively adjusting their strategies, traders who recognize and adjust for high volatility are better positioned to avoid unexpected losses (Natenberg, 1994). The goal is to dynamically adapt to market conditions rather than assume that historical levels of volatility will persist unchanged.

4.5 The Role of Trading Psychology and Discipline

Risk management is not purely about numbers and models—it also involves the psychological preparedness of the trader. The pressure of competing with market makers can lead to emotional decision-making, which often results in overtrading, revenge trading, and deviation from a pre-planned strategy. Alexander Elder’s work in Trading for a Living repeatedly emphasizes the significance of maintaining discipline, controlling emotions, and following a clearly defined trading plan (Elder, 1993).

Developing a trading psychology that accepts small losses in favor of long-term capital preservation is critical. Psychological preparedness can be enhanced by rigorous journaling, reviewing trades objectively, and learning from past mistakes. A disciplined approach is often the difference between success and failure, especially when competing against market makers who consistently possess the advantage of automation and high-speed execution.

5. Behavioral Dynamics and the Sophistication Gap

5.1 The Sophistication of Market Makers

Market makers and high-frequency trading algorithms are designed to be adaptive and agile. They continuously analyze data, adjust prices, and execute trades far more quickly than human traders could ever hope to. This sophistication creates an environment where individual traders may feel at a perpetual disadvantage. Edwin Lefèvre’s narrative in Reminiscences of a Stock Operator hints at how even the most experienced traders can become victims of the “sophistication gap”—the difference in speed, technology, and access to information between professionals and retail traders (Lefèvre, 1923).

5.2 Cognitive Biases and Perceived Control

Human cognitive biases play a significant role in the interactions between individual traders and market makers. For example, the illusion of control—a bias where traders overestimate their ability to predict market movements—can lead to overconfidence and excessive risk-taking. This bias is compounded by a lack of appreciation for the advanced risk management practices that market makers employ.

In Market Wizards, Jack Schwager illustrates that many successful traders eventually learn that their biggest enemy is often their own mind. The psychological battle that ensues when one attempts to “beat” an entity as methodical and technologically advanced as a market maker is fraught with peril (Schwager, 1989). Recognizing and correcting for one’s own biases can be one of the most effective ways to ensure long-term trading success.

5.3 The Danger of Overreliance on Technical Indicators

Many individual traders rely on technical indicators and chart patterns to make trading decisions. While these tools have value, they do not account for the real-time adjustments made by market makers who are also watching the same metrics—often with a far more sophisticated toolkit. Overreliance on technical indicators, without an understanding of the underlying market mechanics and the influence of market makers, can lead to suboptimal decision-making.

Larry Harris’s detailed discussion in Trading and Exchanges makes it clear that market microstructure matters. The micro-level details—such as order flow, liquidity, and execution quality—often override the predictions of lagging technical indicators. In this light, individual traders must complement their technical analysis with a broader understanding of market operations and risk management strategies.

6. Practical Recommendations for Individual Traders

Given the inherent challenges posed by market makers, what practical steps can individual traders take to safeguard their capital? The following recommendations, distilled from the wisdom of several authoritative texts, provide a roadmap for navigating these treacherous waters.

6.1 Accepting the Reality of the Playing Field

The first step in effective risk management is acknowledging the reality: market makers operate with significant advantages. Individual traders should not attempt to “beat” market makers through sheer force of will or by ignoring the underlying market dynamics. Instead, they must adapt to the environment by developing strategies that limit exposure to the forces they cannot control.

6.2 Emphasizing Capital Preservation Over Excessive Profit Seeking

As emphasized in Trading for a Living by Alexander Elder, capital preservation is paramount. This means that before formulating any trade—whether it is long or short—traders must determine the maximum amount of capital they are willing to risk. Keeping losses small preserves capital to remain engaged in the market even when conditions are unfavorable.

6.3 Deploying a Robust Trading Plan

A robust trading plan should incorporate clear entry and exit rules that account for both technical signals and the potential impact of market makers. This includes:

  • Defining Entry Points: Use technical analysis in conjunction with an understanding of market microstructure to choose entry points that minimize the risk of adverse selection.
  • Setting Stop-Losses: Automatically exit losing positions to protect against sudden adverse moves. Stop-loss orders should be adjusted dynamically in volatile conditions.
  • Using Position Sizing: Limit the exposure of any single trade to a small fraction of overall capital. This is critical for long-term survival.
  • Diversification: Do not concentrate capital in a single asset or market. Diversifying across asset classes reduces overall risk.
  • Review and Adaptation: Regularly review your trades to learn from mistakes and adjust your strategy as market conditions evolve.

6.4 Education and Continuous Improvement

Successful trading is an ongoing learning process. Individual traders must invest in their education—not only in technical analysis and market theory but also in the psychology of trading and risk management. Key readings include:

  • Market Wizards by Jack D. Schwager, which offers insights into the mental discipline and strategies of successful traders.
  • Trading and Exchanges by Larry Harris, which provides an in-depth look at market structure and the role of liquidity providers.
  • Options, Futures, and Other Derivatives by John C. Hull, which explains how sophisticated instruments are used to hedge and manage risk.
  • Trading for a Living by Alexander Elder, which emphasizes the psychological aspect of trading and the importance of preserving capital.

6.5 Leveraging Technological Tools

While individual traders may not have the same technological infrastructure as market makers, many platforms now offer sophisticated tools for analysis and risk management. Indicators that measure liquidity, volatility, and order flow can provide an additional layer of insight. Although these tools cannot fully eliminate the risks posed by market makers, they can help traders make more informed decisions.

6.6 Maintaining a Long-Term Perspective

Short-term trading might tempt individuals to try and outsmart market makers on every swing, but maintaining a long-term perspective is vital. Over time, the compound benefits of disciplined risk management, continuous learning, and prudent position sizing can outweigh the occasional short-term losses incurred by market makers’ advantages.

7. Historical Lessons and Case Studies

History is replete with examples of individual traders who fell victim to the sophisticated operations of market makers. The stories found in Reminiscences of a Stock Operator highlight that even the most talented traders can be undone by poor risk management and overconfidence. Jesse Livermore—the subject of Lefèvre’s narrative—experienced both spectacular gains and devastating losses, partly due to his inability to control his risk exposure amidst a dynamic market environment.

Similarly, the rise of high-frequency trading as covered in Michael Lewis’s Flash Boys reveals that modern markets have evolved to a point where speed and technology create formidable barriers for the average trader. These historical lessons emphasize that understanding the nature of market making is not just academic; it is central to the survival and success of any trader.

8. Conclusion

Market makers serve a dual role in modern financial markets—they provide necessary liquidity and market stability, yet they also operate with a set of advantages that can place individual traders at a considerable disadvantage. By quoting both sides of the market, leveraging advanced technologies, and continuously managing their risk exposures, market makers often create conditions that individual traders find difficult to overcome.

This detailed analysis has underscored several key points:

  • Understanding the Role: Recognizing that market makers are not adversaries in a moral sense but participants who are built to profit from an edge in liquidity and information.
  • Risks Beyond the Spread: The risks include adverse selection, execution slippage, and even psychological pressures that lead to overtrading.
  • Robust Risk Management: Individual traders must emphasize capital preservation, deploy strict risk controls, utilize diversification and hedging techniques, and maintain a disciplined trading strategy.
  • Learning from the Best: The wisdom compiled in books such as Trading and Exchanges, Market Wizards, Reminiscences of a Stock Operator, and Trading for a Living offers invaluable lessons that every trader should incorporate.

Ultimately, the message is clear: trying to “beat” market makers in a head-to-head battle is a losing proposition. Instead, individual traders should seek to protect themselves through sound risk management, education, and a healthy recognition of the inherent disadvantages that come with trading in a market dominated by sophisticated liquidity providers. In accepting this reality, the focus shifts from attempting to outsmart the market to ensuring long-term survival and gradual growth in one’s trading career.

Final Thoughts

The financial markets are complex ecosystems where the scales are often tipped in favor of those with the best tools, access, and risk management strategies. The advantage of market makers lies in their ability to continuously adapt and mitigate risk, positioning them as formidable players in any trading environment. For the individual trader, the battle is not about trying to outpace the market makers but rather about minimizing risks and securing every trade with a rigorous discipline and strategy.

By taking the time to educate oneself on market microstructure, risk management techniques, and the psychological aspects of trading—as illustrated in the aforementioned literary works—any trader can build a foundation that not only mitigates risks but also maximizes long-term trading resilience. Remember, success in trading does not stem from beating every market move; it stems from protecting your capital while patiently waiting for opportunities where the inherent risks are in your favor.
